Edit .htaccess to allow PDF?

Hello,

New to WordPress – so I apologize for me amateur question.

I upoaded a PDF to my root folder through FTP, but noticed immediately that each time I try to link to the file, I get a ‘Page Not Found’. I am assuming this is an issue with my .htaccess file? If so – how do I edit to allow links to download PDF files direction?

Here is what I am trying – but is not working:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

<Files ~ “\.(pdf)$”>
order deny,allow
allow from all
</Files>

<FilesMatch “\.(?i:pdf)$”>

ForceType application/octet-stream

Header set Content-Disposition attachment

</FilesMatch>

Thank you!
